Using Transmission Free-Wheeling Lever

IMPORTANT: Avoid damage! Avoid transmission damage:

· DO NOT tow machine.

· Only push tractor by hand, do not use another vehicle to push tractor.


When you need to move the tractor by hand without starting the engine, use the transmission free-wheeling lever:

1. Unlock park brake.

NOTE: The park brake must be unlocked before you can pull out the free-wheeling lever.


M96047

2. Pull free-wheeling control lever (A) rearward until it clicks.

3. Push tractor to desired location.

Lever will automatically return to the operating position when you push down the brake pedal.

Using Weights

c CAUTION: Avoid injury! Add front wheel weights or front frame weights for better front-end stability and steering when using a rear mounted attachment or pulling a cart.

Install tractor front weights to improve stability when operating on slopes.

See your John Deere dealer for the correct weights. Follow instructions provided with weights to install on your machine.

Using Rear Weights


M96047

The rear hitch plate (A) holds four suitcase weights. Use of these weights is recommended when a front attachment, such as snowthrower or blade is used. (See your John Deere dealer for weights.)

Using Tire Chains

Tire chains are recommended for use with snowthrower and, under certain conditions, the front blade. (See your John Deere dealer for tire chains.)

Transporting Machine on Trailer

Be sure trailer has all the necessary lights and signs required by law.

IMPORTANT: Avoid damage! Transmission damage may occur if the machine is moved or towed incorrectly:

· Move unit by hand only.

· DO NOT use another vehicle to move unit.

· DO NOT tow unit.


1. Drive forward onto heavy-duty trailer.

2. Lower mower to trailer deck.

3. Lock park brake.

4. Fasten lawn tractor to trailer with heavy-duty straps, chains, or cables. Both front and rear straps must be directed down and outward from tractor.

5. Strap down hood.

Mowing Tips

The following recommendations will produce the best lawn cut quality and appearance:

· Keep mower blades sharp. Dull blades will tear grass; tips of grass will then turn brown.

· Cutting grass too short may kill grass and let weeds grow easily.

· Adjust cutting height to remove only 1/3 of the grass at a time.

· Mow grass often. Short grass clippings will decay quickly.

· Mow with engine at full throttle.

· Adjust travel speed to match mowing conditions:

· Travel at SLOW speed when you mow thick, tall grass, make sharp turns or trim around objects.

· Travel at MODERATE speed when you mow thin grass.

· Use a different mowing pattern each time you mow. Overlap mowing paths 50 to 100 mm (2 to 4 in).

· Drive over ridges and through shallow ditches straight-on, not at an angle.

· A thick layer of mulched leave can prevent sunlight from getting to grass and smother it. Taller grass heights allow mulched leaves to dispense easier in lawn. Mulch leaves several times if needed.

· Use a thatcher in late spring or summer to pull up dead grass and aerate ground.
